It is keyed so you cannot put the connector on wrong.

In later DE games, Stern put an extra 2 pins on this connector to allow for unregulated 12V to be used for toys. I think only one of the 2 extra pins was ever used, and only on a few games (LAH I am thinking).

Never try to teach a pig to sing. You will end up only wasting your time and annoying the pig.... But here I go anyway trying to teach a pig to sing....

DE power supplies go bad. Rottendog power supplies go bad. I can use "Crashes" methods and say I know a guy who had a Dell computer and it didn't work so all Dell computers will go bad.

Crash is obviously a "technical" guy with comments like "Tim refuses to admit and correct the voltage regulator issue, there is just no excuse for using components out of spec like that."

Hey Mr. "Crash" which spec am I not meeting?

Watch. The lack of response on which spec I am not meeting will be defining!

Here is a link to the regulator I am using. http://www.onsemi.com/pub_link/Collateral/LM337-D.PDF

Please do not be so simple as to assume that "differential" voltage of 37V and output voltage of 37V is the same. Call me if you need to know the difference.

Wow. Two phone calls from happy customers. I was asked to post my schematics for this board to "help" "Crash" post how I am using components "out of spec".

Here is the link to the schematic:

Crash, I am waiting for your call. Since the phone still ain't ringing I assume it still aint you?

Facts? What facts?

What part of the design doesn't make sense?

Please be specific.

The design hasn't been updated? It is a complete redesign of the original DE design.

Either you are just repeating what other ignorant people say, or you are ignorant.

You specifically say: "Tim refuses to admit and correct the voltage regulator issue, there is just no excuse for using components out of spec like that."

Your statement. Where in my design am I "using components out of spec like that"?

Your statement. Please specifically tell me where I am "using components out of spec" , or say your wrong (which you are).

Anything I say, I am willing to back up with specifics. Are you?

I give up.
